Fox guns which remain off safe because the safety pushrod has been removed will also let down their hammers slowly upon pulling both triggers after opening and cocking. The force of hammer springs relaxing to let the hammers down allows the hammer toes to apply pressure to the cocking rods and Viola--"self-closer". Stored energy does not care that the normal operation of the mech is reversed. Both of my Lefevers do so with the safety held to the rear and triggers pulled.
Ed, some of us have been trying to feed you humble pie and peanut butter for several days and it ain't working so what the heck, I guess your opinions here are as good as anyone's as they're free for the taking or leaving just like anyone's.
